Hi Richard,

The document weights are very cool!

Just a quick note.
It works only with slot number 0, but it doesn't work
so far with any other slot. I only added these lines
to my code:

xapian_document.add_value( 0, Xapian::sortable_serialise(weight) );

And right before Xapian::Enquire():

Xapian::ValueWeightPostingSource xapian_valueweight( 0 );
xapian_query = Xapian::Query( Xapian::Query::OP_AND_MAYBE,
                 xapian_query, Xapian::Query(&xapian_valueweight) );

Thanks
Marcus
